Claim: The conflicts between Anne and Mr. Dussel arise primarily from their differing personalities and the stress of living in close quarters during a time of crisis.

Evidence: In Act I, Scene 4, Anne's lively and outspoken nature clashes with Mr. Dussel's more reserved and anxious demeanor, leading to tension when Anne seeks attention and interaction, while Mr. Dussel prefers a quieter environment. Additionally, in Act I, Scene 5, their disagreement escalates when Anne's behavior disrupts Mr. Dussel's need for peace, causing him to express his frustration openly.

Reasoning: These conflicts highlight the challenges of cohabitation under stressful circumstances, as Anne's youthful exuberance conflicts with Mr. Dussel's need for order and calm. Their interactions illustrate how the pressures of their situation exacerbate personal differences, leading to misunderstandings and heightened emotions.
